HITC Sport understands Crystal Palace are leading the race for Turkish international.

Crystal Palace are hopeful of beating the transfer deadline to sign Besiktas forward Cenk Tosun, HITC Sport understands from sources close to the club.
Tosun has been linked with a number of Premier League sides after impressing for club and country in the last couple of years.
Tosun, who was born in Germany, has scored five goals in 18 appearances for Turkey and he netted 24 goals last season to help Besiktas win the Super Lig title.
Crystal Palace have been searching for striking reinforcements all summer as they want to bring in cover and competition for Christian Benteke.

A host of names have been linked with a move to Palace, but Tosun is understood to have emerged as the Eagles’ top target.
Palace boss Frank de Boer has stepped up the club’s interest in Tosun with the side losing all three Premier League games so far this season and failing to score in those encounters.
Besiktas are reluctant to lose Tosun, but accept they can make a major profit on a player they signed on a free transfer in 2014.
